YARN SPOOL.

Application filed October 5, 1923.

To all whom t may concer/nv.'

Be it known that I, EDGAR F. I-IATHAWAY, a citizen of the United States, and resident of Wellesley, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Yarn Spools, of which the following is a specilication. 4

This invention relates to yarn spools especially of the type used for carrying the yarn in tube frames that are employed in tutt weaving, and is intended to provide a simple and conveniently operated construction for the spool journal so that the spool may be mounted in closed bearings formed in the bearing brackets carried by the tube 'frame or other support so as to readily permit the retracting of the journal preparatory to removing` the spool.

To this end the invention comprises, generally speaking, a ournal construction characterized by an axially movable journal pin mounted in the end of the spool and normally projecting beyond the head or end of the spool to rest in its bearing, combined with retracting means located between the spool and the bearing bracket so as to be readily accessible to the attendant when he has occasion to remove the spool from its bearing. These and other features of the invention will be described in the following specification and will be defined in the F parts of the ournal construction.

Figure 3 is an end elevation showing the relation of the bearing bracket to the spool end and journal.

In the present instance I have shown a spool whose barrel l, is of metallic tubing to whose end is secured a metallic flanged disk or head 2, forming a cover for the open end of the tubular barrel.

Concentrieally with the spool I mount an Serial No. 666,837.

axial hollow casing 3, which is securely fastened to the head of the spool so as to hold it firmly in place.

Inside this hollow inwardly projecting casing 3, is mounted a slidable or telescoping sleeve 4, which has bearing against the interior wall of said casing to allow the sleeve to slide in and out. The sleeve is provided with a transversely or radially projecting disk 5, which preferably is of greater width than the upper portion of the bearing bracket c, of the tube frame in which the spool is mounted to permit unwinding of the yarn thereof.

In this instance an elongated axial pin 6, is preferably provided with a head 7, at one end to limit its outward movement by contact with the inner end of the hollow casing 3. The outer end of the pin passes through the sleeve 4 and the disk 5, so as to project some distance beyond the disk to permit it to lie in the bearing opening of the bearing bracket. The sleeve with its disk flange 5 is secured to the journal pin 6, in any suitable manner as by a transverse fastening pin 9. A helical spring 8, coiled around the ournal pin, is seated against the inmost wall of the casing 3 and exerts an outward thrust against the flange sleeve, thereby tending to yieldingly force outward both the pin and its guide sleeve, the flange 5 being located preferably far enough from the outer end of the journal pin to avoid cont-act with the bearing bracket when thrust outward to normal operative position. It will be seen that with the arrangement described the disk is readily accessible aroundthe greater part of the upper end of' the bearing bracket so that it can be pressed inward by the finger of the attendant, thereby serving as a retracting member for withdrawing the journal pin entirely out of the bearing opening in the bearing bracket c, thus permitting'the spool to be lifted bodily out of the tube frame.

This construction enables the bearing brackets which support the 'spool above the carrier bar a, to be made with closed ,bearing perforations from which the spool can be readily removed by the retraction of one of the journals without the use of any special appliance or tool.

l Heretofore it has been customary to use cgi a plunger type ot supporting journal for the spool and in conjunction therewith a closed bearing opening in the spool-supporting bracket. With such construction the attendant usually had to carry some special teol for forcing the journal inward by end pressure thereon until it cleared the bearing bracket, and as the suspension hanger arms lay very close across the end of the spool journal this was a rather bothersome and inconvenient operation.

By the present construction no special tool is required, and the operator by merely pressing inwardly on the flange or disk 5, easily withdraws the journal from engagement with the bearing bracket to allow it to completely clear the bearing bracket in the act of removing, one linger of the hand to grasp the spool to pull it out being suf- 'icient to retract the journal pin.

The tube trame, as shown in Figure l, is of well known type or' construction and embodies the longitudinal tube-carrying bar a and the suspension hanger b from which projects upwardly and inwardly the spool bearing` bracket c.

that I claim is:

l. A yarn spool embracing in its construction, a yarn-receiving barrel, an end head secured thereto, an axially movable journal concentrically mounted in the spool and provided near its projectng end with a lateral projection arranged outside of the head to be accessible for retracting the journal from its external bearing, substantially as described.

2. A yarn-spool for a. tube frame or the like, embracing in combination a spool head and barrel, and a springpressed outwardly projecting journal mounted axially of the spool and provided near its outer end with means by which the journal may be re tracted axially fromits bearing to permit the removall of the spool, substantially as described.

3. A yarn spool for a tube frame or the like, embracing in its construction a spool head and barrel, a retractile journal yieldingly pushed outward :tor engagement with its bearing, and retracting means connected with the journal and projecting laterally beyond the periphery of the bearing member in position accessible to the attendent, whereby the journal may be conveniently withdrawn from the bearing to permit the removal of the spool, substantially as described.

4. A journal construction for a yarn spool embracing an axial journal pin mounted in the. end of the spool, a spring acting to normally press the journal pin outward to operative bearing position, a collar secured on said pin. to project laterally trom the pin adjacent to a pin-supporting bearing member, and means limit-ing the outward movement of the pin, substantially as described.

5. A yarn spool provided at its end with an axial bore, an axially movable journal pin mounted therein, a radially hanged sleeve secured to the pin ali'ording a guiding bearing with the bore of the spool, a compressed spring surrounding the pin and thrusting outwardly against said sleeve, and means for limiting the outward endwise movement of said pin and its sleeve, substantially as described.

6. In a yarn spool the combination ot' a tubular metallic barrel, a circularI metallic head secured thereto so as to cover' the open end of the tubular barrel, a tubular casing secured centrally of the head to project axially inside the barrel, a flanged sleeve mounted to slide axially in the casing, a. journal pin movably axially and having guiding support in the inner end of the casing and secured in the sleeve, and a spring acting normally to press the journal pin outwardly into a supporting bearing, substantially as described.

7. A journal construction for a yarn spool, embracing a journal pin mounted to telescope into the end portion of the spool, a helical spring acting to thrust said journal pin outwardly beyond the head of thepspool, and a transversely disposed retracting disk connected with the pin beyond the head of the spool, substantially as described.

8. The combination of a yarn spool comprising a barrel and head, an external bearing bracket, an axial journal slidably mounted in the spool to enter the bearing bracket, and journal-retracting means located between the spool head and the bearing member and connected with the spool journal, substantially as described.

In witness whereof, I have subscribed the above specification.
